| cobra venom cofactor | <enzyme> A glycine-rich, heat-labile beta-glycoprotein found in blood. It is a proactivator of complement 3 in the alternate pathway of complement activation. Factor b is converted by factor d to c3 convertase. Registry number: EC 3.4.21.47 (12 Dec 1998) |
|---|
| cobra venom factor | A component of cobra venom that renders C3 proactivator (properdin factor B) susceptible to factor D of the properdin system, leading to activation of C3 and other components of complement and lysis of unsensitised erythrocytes. (05 Mar 2000) |
|---|---|
| direct lytic factor of cobra venom | A polypeptide of 62 residues; action on cells is similar to that of melittin in that it promotes disruption of membranes; used as an investigational antirheumatic agent. Synonym: cobra toxin, direct lytic factor of cobra venom. (05 Mar 2000) |
| molybdenum cofactor | A complex of molybdenum and molybdopterin required for a number of enzymes. A deficiency of this cofactor will result in lower activities of sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase causing elevated levels of sulfite, thiosulfite, xanthine, etc. (05 Mar 2000) |
| cofactor | <biochemistry> Inorganic complement of an enzyme reaction, usually a metal ions. See: coenzyme. (18 Nov 1997) |
| platelet cofactor I | A coagulation (clotting) factor. Classic haemophilia (haemophilia A) is due to a congenital deficiency in the amount (or activity) of factor VIII. Factor VIII is also known as antihemophiliac factor (AHF) or antihemophiliac globulin (AHG). The gene for factor VIII (that for classic haemophilia) is on the X chromosome so females can be silent carriers without symptoms and males can be haemophiliacs. (12 Dec 1998) |
| platelet cofactor II | <chemical> Storage-stable blood coagulation factor acting in the intrinsic pathway. Its activated form, ixa, forms a complex with factor viii and calcium on platelet factor 3 to activate factor x to xa. Deficiency of factor ix results in christmas disease (haemophilia b). Chemical name: Blood-coagulation factor IX (12 Dec 1998) |
| heparin cofactor II | <chemical> A sulfated plasma protein with the mw of approximately 66kda. The protein is an inhibitor of thrombin in plasma that is activated by dermatan sulfate or heparin. It is a member of the serpin superfamily. Pharmacological action: serine proteinase inhibitors. Chemical name: Heparin cofactor II (12 Dec 1998) |
| cobra | A genus of poisonous snakes of the subfamily elapinae of the family elapidae. There are six recognised species, all inhabiting africa except the asiatic (indian) cobra, naja naja. Some species "spit" their venom into the eyes of their "enemies". So-called spitting cobras show a high degree of accuracy in aiming for the eyes. The ringhals, the most highly specialised of the spitting cobras, is limited to southern africa. Its spray destroys eye tissue and can cause blindness; its bite can cause death. (moore: poisonous snakes of the world, 1980, p80) (12 Dec 1998) |
| cobra neurotoxins | Toxins, contained in cobra (naja) venom that block cholinergic receptors; two specific proteins have been described, the small (short, type I) and the large (long, type II) which also exist in other elapid venoms. (12 Dec 1998) |
| cobra toxin | A polypeptide of 62 residues; action on cells is similar to that of melittin in that it promotes disruption of membranes; used as an investigational antirheumatic agent. Synonym: cobra toxin, direct lytic factor of cobra venom. (05 Mar 2000) |
| cobra venoms | Venoms from snakes of the genus naja (family elapidae). They contain many specific proteins that have cytotoxic, haemolytic, neurotoxic, and other properties. Like other elapid venoms, they are rich in enzymes. They include cobramines and cobralysins. (12 Dec 1998) |
| black widow spider venom | Potent neurotoxin that induces catastrophic release of acetylcholine from presynaptic terminals of cholinergic chemical synapses. (18 Nov 1997) |
| venom | <chemical> A toxic secretion in animals that is actively delivered to the target organism, either to paralyse or incapacitate or else to cause pain as a defence mechanism. Commonly include protein and peptide toxins. (12 Jan 1998) |
| venom haemolysis | That caused by haemolytic material in the venom of various species of snakes or other venomous animals. (05 Mar 2000) |
| Russell's viper venom | A venom used as a coagulant in the arrest of haemorrhage from accessible sites in haemophilia. (05 Mar 2000) |
